Problems solved by technology

[0003] The technical problem solved by the present invention is to design an integral hanging string crimping die, change the structure of the original 1-2 teeth asymmetrical crimping die, and adopt a crimping groove with a larger force-bearing area to improve the service life of the die. Direction requirements, solve the problem of broken wires and strands affecting line safety due to crimping damage during the operation of the overall suspension line of electrified railways

Abstract

The invention discloses an integral dropper pressing mold. The pressing mold comprises a sub mold I and a sub mold II symmetrically matched; the sub mold I includes a sub mold body I, a connecting column I formed at the end part of the sub mold body I, and guide blocks I respectively arranged on two sides of the sub mold body I; a mold cavity I is formed in the sub mold body I; the sub mold II includes a sub mold body II, a connecting column II formed at the end part of the sub mold body II, and guide blocks II respectively arranged on two sides of the sub mold body II; a mold cavity II is formed in the sub mold body II; the mold cavity I and the mold cavity II define an elliptic pressing hole; and two annular bosses are symmetrically arranged in the mold cavity. The integral lifting chord pressing mold changes a traditional 1-2-tooth asymmetric pressing mold structure, adopts a pressing groove with a larger stress area, prolongs the service life, has no direction requirements in use, and solves the problem of influence on the circuit safety by wire and strand breakage caused by pressing damage in the integral dropper circuit operation process of an electric railway.

Description

technical field [0001] The invention relates to the technical field of catenary equipment for electrified railways, in particular to an integral hanging string crimping mold. Background technique [0002] As one of the important components in the electrified railway catenary, the integral suspension string is also the main suspension part, which plays a vital role in the electrified railway catenary. At present, the integral suspension strings used in the electrified railway catenary, and the suspension string crimping tubes are mostly crimped with pointed dog-tooth molds, that is, the 1-2 teeth at the crimping tube are asymmetrically crimped, and the force and deformation of the two tooth sides It is 1 / 2 of the single tooth, mainly relying on the crimping method of point or line contact, so that the stress is concentrated during crimping, the axial force is uneven, the stranded wire is bent, and an additional bend is formed at the outlet of the crimping point. moment, resu...
